All releases of unpkg

Release Notes: Unpkg has been entirely rewritten in Python. It now works with multiple packages at once, and extracts 10.5-style packages (as well as nested ones, and in 10.4 as well). Unpkg has also been upgraded to a WebKit-based interface, over the old CocoaDialog one.

Release Notes: unpkg is now a Universal Binary. It sports a
highly-revised backend and
a completely new interface, with Cocoa dialogs,
progress bars, file
choosers, and error messages instead of the old
text console output.
